Question 346291
Let x = number of stoves & refrigerators sold &


the number of air conditioners = double that of stoves and refrigerators 


combined


= 2(x+x)


= 2(2x)


= 4x


Then 600(4x) + 500x+400x = 16 500


2400x + 900x = 16 500


3300x = 16500


x = 16500/3300 = 5


So, x = 5.


Therefore 5 stoves are sold , 5 refrigerators are sold and 20 air conditioners are sold.
